摘要： A controller for a gradient sequential compression system is provided for inflating a plurality of inflatable chambers of one or more compression sleeves according to several different modes of operation. A mode of operation may define the number and selection of chambers to be inflated, the pressurization levels, the pressurization time, or the sequence of chamber inflation. To enable the controller to automatically perform a designated mode of operation based on the type of compression sleeve connected, a new and improved connecting device is provided. An indicator on an interface connector associates a predetermined mode of operation with the interface connector. A sensor associated with a complementary connector identifies the mode of operation associated with the interface connector. It is contemplated that the universal connecting device can be used for any type of system, not just controllers for a gradient sequential compression system.

摘要： Modular expandable hyperpolarizers include a central control module and at least one optical pumping module that can be expandable to a plurality of optical pumping modules that can be separately operated depending on the capacity demands at the production site (hospital, clinic and the like). Methods for producing blended polarized gas products include introducing a pre-packaged pre-mixed amount of a polarizer-ready blend of unpolarized gas. Methods for producing the polarized gas can be carried out at the point of use site and the production run according to patient load. Other methods consider the patient load and automatically schedule the hyperpolarizer to yield the desired polarized gas doses to support the patient and/or MRI/NMR equipment schedule.
